Abstract
The utility model discloses a flask, and belongs to the technical field of experimental tools. The flask comprises a flask body, wherein a plurality of axial columns are arranged on the inner wall of the flask body; the section of each column is 5-10 mm; each column extends to the flask opening along the bottom of the flask; a stopping net is arranged between every two columns. The flask has the characteristics of simple structure, high convenience for use, and high safety and reliability.
Description
Technical field
The utility model relates to a kind of experiment appliance, especially a kind of beaker.
Background technology
At present, obtaining method of testing for fabric pH value is generally accurate clip cloth specimen, and shreds, in beaker beaker, pour distilled water into, on electric furnace, boil 10 minutes, put into the cloth specimen shredding, cover beaker with surface plate, continue to boil and coolingly after 10 minutes just can measure pH value.In practical operation, if the unit mass of cloth specimen is too small, put into cloth specimen in beaker just more, sometimes even fill up whole beaker, carrying out in the process of above-mentioned poach cloth specimen, because beaker inner surface is smooth, make cloth specimen be close to walls of beaker, cause the gas of beaker bottom to overflow, thereby occur that bumping ejects the surface plate covering on beaker, cause surface plate fragmentation, sometimes also can scald because of carelessness experimenter, when serious, bottom gas pressure is excessive also can cause beaker explosion, abnormally dangerous.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of beaker for above the deficiencies in the prior art, and this beaker has the features such as simple in structure, safe and reliable.
The utility model solves the technical scheme that its technical problem adopts: a kind of beaker, comprise cup, on described cup inwall, be provided with some axial cylinders, described pole section diameter is 5-10mm, described cylinder extends to beaker rim of a cup place along beaker bottom, is provided with a grade net between described cylinder.
The beneficial effects of the utility model are: in heating process, in the space that gas meeting edge shelves net and beaker inwall form, overflow, thereby effectively prevent that the phenomenon of bumping or explosion from occurring, and very safe and reliable; What be provided with grade mesh is to stop that cloth specimen contacts with walls of beaker, and gas like this that be conducive to beaker bottom is discharged smoothly.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model cylinder and a grade connection diagram for net.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described below.
As depicted in figs. 1 and 2, a kind of beaker, comprises cup 1, on described cup 1 inwall, is provided with some axial cylinders 2, and described cylinder 2 diameter of sections are 5-10mm, and described cylinder 2 extends to beaker rim of a cup place along beaker bottom, between described cylinder 2, is provided with grade net 3.
